It is compatible with various media including hydraulic oil, ordinary water/deionized water, solvents, mild chemicals and liquefied gases, and is widely applied in fields such as pressure testing, fluid transfer, wellhead control and industrial power.

Product Information

Product Overview
Single-Drive Single-Acting · Maximum Output Pressure 25,000 psi (1723 bar)
The M3 Series is a single-drive single-acting air-driven booster pump launched by HIGH·PA. The pump head and piston are made of stainless steel, featuring a lightweight, compact, robust and reliable structure. Powered by compressed air, it amplifies pressure based on Pascal’s law of pressure transmission through the area difference between a large-area drive piston and a small-area booster plunger, delivering stable high-pressure liquid output on site where electricity and high-pressure power sources are unavailable.

This series offers 9 boost ratios (5.6:1 ~ 237:1), with a maximum output pressure of 25,000 psi (1723 bar) and a maximum flow rate of 8.3 L/min. It is compatible with various media including hydraulic oil, plain water / deionized water, solvents, mild chemicals and liquefied gases, and is widely used in pressure testing, fluid transfer, wellhead control and industrial power applications.

Applicable Media: Hydraulic oil, water (plain water or deionized water), solvents, mild chemicals, liquefied gases, etc.

Product Features
  • Single-drive single-acting structure, lightweight and compact for easy installation
  • 9 optional boost ratios to meet multi-level pressure requirements
  • Maximum output pressure 25,000 psi (1723 bar), maximum flow rate 8.3 L/min
  • Optional seal materials for different media and working conditions
  • Drive air pressure range: 10 ~ 125 psi, convenient for on-site connection
  • Automatic pressure holding and replenishment: automatically stops when force balance is reached, maintains pressure with zero air consumption, and restarts automatically to compensate for pressure loss upon leakage
  • Pure air-driven design, no electric arcs or sparks, safely suitable for explosion-proof and hazardous areas

Product FAQ

A gas booster is a pneumatically driven intensifier that uses low-pressure drive gas (e.g. instrument air, typically 1–10 bar) on a large-area piston to compress process gas on the small-area end, producing high-pressure output. It requires no electricity, produces no sparks or heat, and is ideal for boosting, transferring, cylinder charging and gas recovery of nitrogen, natural gas, argon, helium, oxygen and hydrogen in hazardous areas. HIGH-PA air-driven gas boosters reach up to 39,000 psi (≈2,689 bar).
